PLOW-FRAME STRUCTURE.

Specification of Letters Patent.

Patented J an. 11, 1916.

Original application led July 16, 1914, Serial No, 851,344. Divided and this application filed July 9, 1915. Serial No. 38,898.

An object of this invention is to provide a plow frame adapted for use in connection with a. sulky plow of applica-nts construction as fully set forth in applicants former application.

A further object of this invention is the provision of a frame of the character hereinafter described, having a Vpair of oppositely disposed U-shaped brackets, one of said brackets being adapted to strengthen the rear extremities of the frame, while the other of said brackets is provided for the reception of the free end of a plow beam or the like.

A still further object of this invention is the provision of a frame having an eXtension formed thereon the forward end thereof, adapted tohave mounted thereupon a draft attachment, or the like, while at one side and at the rear end thereof, said frame is bent so as to produce an oblong supporting means. A

lith the above and other objects in view, this invention resides in the novel features of construction, formations, combinations, arrangements of parts to be hereinafter more fully described and illustrated in the accompanying drawings in which Figure l is a top plan view of my iinproved plow frame, illustrating` in dotted lines the wheels and coperating parts. Fig. 2 is a front elevation of the same. Fig. 3 is a detail perspective view of one of the rear extremities of said frame, illustrating the connection of the bearings therewith. Fig. 4 is a longitudinal sectional view of said frame taken on line 41-1 of Fig. 1.

Referring to the accompanying, drawing by similar characters of reference, the numeral 10 denotes in general my improved plow frame which is substantially Ueshaped in construction and composed, of a plurality of rails 11 and 12. These rails 11 and 12 are substantially secured together at the for ward end thereof by any suitable means as indicated by the numeral 13 but are suitably spaced apart at their rear terminals as clearly illustrated by Fig. 1 of the accompanying drawing and as designated by the numeral 111. This space 111 being produced by bending the rail 11 at right angles as indicated by 15 then bending the same again as indicated at 1G thus bending the same into pa allel-relation again with the other rail 12.

As clearly illustrated by Fig. 1 of the drawing it is to be clearly seen that the latter rail 12 abruptly terminates at its rear extremity at which point it is connected through the medium of a U-shaped bracing bracket 17 and bolts 18 and 19 with the former rail 11. |This rail 11 as illustrated does not terminate at the point of connection with the bracing bracket 17, but continues on and is again bent at right angles as indicated by 2O and thence back upon itself proper as indicated by the numeral 21 and secured thereto by the same bolt 1S that connects the bracing bracket 17 with the rail 11. Thus it will be readily seen that the rear end of the rail 11 is so bent as to form an extension at right angles to the frame which provides a supporting means 22 having bearings 28 formed therefrom adapted to receive the axle 24e of the wheel 25. This supporting means also provides a suitable and convenient location for the operators seat '2G which is secured thereto by any suitable means.

Secured to the forward end of the frame by bolts 27 or the like is a downwardly eX- tended U-shaped bracket 2S adapted to receive the free end of a plow beam 26 thus producing a means for limiting the undesired movement of said beam when in operation but at the same time allowing sufiicient play for the same. Intermediate the length of this plow beam, the same is suitably supported by a bracket 29 carried upon a lever 30 pivotally mounted upon the rail 11 by means of the bolt 18. The terminal 31 of this lever 30 provides a supporting means for a second wheel 32 and as a second lever 33 is pivotally mounted upon the rail 12 and provides a supporting means for the terminal 31 of the lever 30 it will be readily understood that with a frame of this construction but one of the two wheels that support the same is connected with the frame proper. l

The rails l1 and l2 being secured together at the forward end thereof and extending in advance of the frame proper produce an extension A upon which may be mounted a draft attachment Bet pivotally mounted between a pair of supporting members 35 which permit the oscillation of said attachment, which is guided in its course of movement through the medium of a curved arm 36 mounted thereon. The greatest of stress should be laid upon the simplicity and efticiency of this frame structure as it is to be particularly7 used in connection with a sulky plow and it is thought that the above description together with the drawings and by referring to applicants former application will enable those familiar with this art to readily understand the construction of this frame, as well as enabling them to realize the many advantages of the same.

It may be still further stated that a frame is herewith provided that is composed of a series of U-shaped members each produced for a. special purpose and having connections with each other thus composing this frame.

It should further be understoodin this construction that various minor changes in the details of construction may be resorted to within the scope of the appended claims, without departing from or sacrificing any of the advantages of this invention.

What I claim is l. In a device of the character described comprising a frame composed of a plurality of rails connected to each other at their forward ends, one of said rails being straight and having a means connected at the rear end for supporting a wheel axle, the other of said rails being bent at right angles a limited distance from the forward ends of said rails, then bent again into parallel relation with said straight rail, extended at right angles to the parallel portion, then bent again into parallel relation with said straight rail and extended inward to join the first parallel portion in line with the rear end of the straight rail, thus constituting an extension at right angles to said frame and having means connected therewith for supporting a second wheel axle, a bracket connecting both of said rails at the rear ends thereof and a second bracket secured to the first-mentioned right angular portion of the second-mentioned rail for the reception of the plow beam or the like.

2. In a device of the character described comprising a frame composed of a plurality of rails connected to each other at their forward ends, one of said rails being straight and having al lever pivotally mounted at the rear end for supporting a` wheel axle, the other of said rails being bent at right angles a limited distance from the forward ends of said rails, then bent again into parallel relation with said straight rail, extended at right angles to theparallel portion, then bent again into parallel relation with said straight rail and extended inward to join the first parallel portion in line with the rear end of the straight rail, thus constituting an extension at kright `angles to said frame and having a plurality of bearings connected therewith for supporting an axle having a wheel mounted thereon, a bracket connecting both of said rails at the rear ends thereof as a reinforcing means for said frame, a second b acket secured to the first-mentioned right angular portion of the second-mentioned rail for the reception of a plow beam or the like and a second extension formed at the forward end of said rails by their contacting engagement with each other to the first right angular bend of the second-mentioned rail for the purpose of providing a supporting means for a draft attachment.

In testimony whereof I afiix my signature in presence of two witnesses.
